What is a solid-state circuit breaker (ABB)?

A technological breakthrough by ABB – a solid-state circuit breaker – will enhance performance of renewable energy solutions, industrial battery storage solutions and so-called edge grids.

What is a circuit breaker?

A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.

What is a solid-state circuit breaker?

The solid-state circuit breaker will be around 100 times faster than traditional electro-mechanical breakers. Its speed maximizes the performance of power distribution systems, while maintaining service continuity. The new ABB breaker will also improve safety and protection for people and equipment.

What is a power defense circuit breaker?

Its basic function is to interrupt current flow after protective relays detect a fault. Take an indepth look at circuit breakers with a special emphasis on the Eaton's most technologically advanced circuit breaker, the Power Defense molded case circuit breaker.

Why should you use a solid state circuit breaker?

Electric Transportation: In marine vessels, for example, the solid-state circuit breaker will make it possible to keep systems up and running without much interruption, as it is possible to disconnect just a faulty zone while keeping the rest of the electrical distribution system running; complete system shutdowns will be a thing of the past.

How does Eaton circuit breaker work?

Eaton’s residential, miniature and molded case circuit breakers utilize over-toggle mechanism. The two-step stored energy mechanism is used when a large amount of energy is required to close the circuit breaker and when it needs to close rapidly. The major advantages of this mechanism are rapid reclosing and safety.
